Universal Slate Coaster Laser Engraving Jig – Holds Four 4" Coasters | Batch engrave four 4-inch slate coasters with fast, repeatable positioning.

Increase your engraving efficiency with the Universal Slate Coaster Jig from The 328 Collective. Designed to hold four standard 4-inch slate coasters, this production fixture works with both round and square coaster blanks. The universal design allows it to be used with virtually any CO₂, diode, fiber, or UV laser engraver by establishing your own machine reference point. Because slate is a natural material, coaster dimensions can vary slightly between manufacturers and even between production batches. This jig is designed to accommodate those normal variations. Some coasters may fit more snugly than others, but all standard 4-inch coasters should seat properly for accurate engraving. Perfect for personalized gifts, craft businesses, promotional products, and production engraving.
